TO ALL w en 11 MAY CONCERN:

Be it known that I, ADRIAN VJBLORR, of Steeleville, in the county of Chester, and State of Pcnnsylvania, have invented an Iipprovcd Self-Acting, Railroad Car-Coupling; and I do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, and'to the The nature of my invention consists in so arranging the couplings of railroad cars that when they are brought in contact the pin of the one shall drop into the link'of the other, completing their attachment, and

avoiding the necessity and l'isk'of any persongoing betweenthe, bumpers for the purpose, asis'done at present.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operationp I construct my COUPlI-Hg of wrought iron, or any other suitable material, in the ordinary form, by using two plates, A and B,figs'.'1 and 2. These plates are flared out at the mouth of the coupling so as to give greater room for the introduction of the link L, and are united one above the other by means of upright side and end pieces, h and s s. Fastened at the mouth of the coupling, and extending some distance around it, is the piece G. This piece 0 serves the purpose of astop or bumper when thecars come together, and has, from its upper side an arm, E, running backwards, through which the pin-P operates. This arm E serves to keep the pin P steady when the car is uncoupled. I place in one side of the coupling D,"fig. 3. This piece D has attached to its upper edge a horizontal wing, G, and moves on the pivots p p. This piece, when in its place, is so arranged thatits wing G shall rest against the lower side of the upper plate A of the coupling, its object-being to close the hole in this plate, when the car is uncoupled, and keep up the pin P.' When the link L is out of the coupling the movable piece D, working on its pivots p 1), and acted on by the spring S, forces the wing G under the hole in the upper plate A, and keeps up the pin 1, and when the link L is forced into the coupling it necessarily pushes out this movable piece D and removes the wing G from under the hole, when the pin P drops into its place, and the link is secured. This wing G also serves the purpose of keeping the pin P from coming out when the car is in-motion. I place in a proper mortise, in the lower plate B of the coupling, and at the necessary distance from its mouth, a Tsheaded square bolt, a. This bolt has its head on one-side, and is made to move up and down by means of the spring g l. It is kept in its place by an arrangement'seen at b, or in any other suitable manner. The head of this bolt 0; is made to hold the end of the-link L while tho-car is being 'run together in the act of coupling. As soon as the pin P of the other coupling drops, and the cars separate the length of the link, the link is drawn from under this head, and the head a sinks level with the upper surface of the lower plate 13 of the coupling, thus being kept out of the way of the free play of the link while the train is in motion. The rods I I, at the ends of the coupling, are merely for the purpose of attaching them to the trucks, as is at present done. i v I I From the foregoing description of my invention the following will necessarily be itsoperation: When the T-headed bolt (4 is raised up, and the link L placed under it, as is done in fig. 1, the pin P being in its place, vand the other'coupling being in thecondition as represented in fig. 2, that is, the pin P raised, and its point resting on the wing Gr of the movable side-piece D, the cars being now brought together, the free end of the link L enters the mouth of the approaching coupling, presses out the movable piece D, and removes the wing Gfrom under the end of the pin P, which drops through the link and secures it; The carsbeiug now drawn forward, the link L is drawn from under the T-headed bolt a, which-,by means of the spring 5 isibrought level with the surface of the lower plate B,.and of course out of the way. v

I am aware that self-acting car-couplings are not new; I 'therefore wish it to be understood that I make no claim to be the originator of this idea; but what I do claim as my-'invention,-and wish to secure by Letters Patent, is-

In an automatic car-coupling, the combination of the stop D=with the spring Send the link-supporting device a with its spring 9, all constructed, arranged, and operatingas described, for the purpose set forth.
